| 摘 要： | 危岩体是影响人类生命财产安全与工程活动的自然地质灾害之一。对危岩体的勘察、稳定性评价与防治是地质灾害防治的研究难题。受危岩体复杂地质特征影响,南门湾危岩体由20余个危岩块体组成,其防治设计存在一定工程风险。本文通过分析岩体裂隙系统发育状况,在W6危岩单体稳定性研究的基础上,建立了赤平投影法评价危岩体稳定性的判断标准与南门湾危岩体的稳定性分区,提出了对应的防治措施建议。本文的稳定性研究具有一定的理论意义,对该危岩体的防治工程具有指导意义。

| Abstract: | Unstable rock blocks are one of the geological natural hazard sources and can have a great influence on human life and engineering activities.The investigation of the unstable rock blocks,the evaluation of their stability and thier prevention measure are difficult tasks.The Nanmenwan unstable rocks have 20 blocks.The controlling design for the unstable rock blocks is very difficult for their complex geological characteristics.In this paper,in order to treat the unstable rock blocks,a stability evaluation criterion for unstable rock blocks at Nanmenwan is established on the basis of the study for the W6 unstable rock block with stereographic projection method.At the same time,the stability zone division at Nanmenwan is carried by the analysis of rock fractures development.At last,the control measures for unstable rock are also proposed for a guiding significance for the project. |
